Questions
Is it free?
Yes. Free tools need no account: up to 20 runs a day, 5 files at a time, 50 MB a file. Pro removes the limits.
Is my password kept?
No. It is used for this run only and is not saved or shown anywhere.
What happens to my files?
They are used for this run only and deleted automatically. Nobody looks at them, and they are never used to train AI.
